A hydraulic valveinongova "mudziyo unogadziriswa hydraulic resistance", hapana chimwe, kana zvishoma. Yese mavharuvhu e hydraulic anofanirwa kukwanisa "kugadzirisa hydraulic resistance", uye anogona chete kuita izvi, pasina kusarudzika. Kutanga kubva pachinhu ichi, zviri nyore uye zvakakwana kunzwisisa mavharuvhu e hydraulic, kunyanya, mamwe mavharuvhu ekubatanidza mumichina yekuvaka, mamwe mavharuvhu e hydraulic ane zvimiro zvakaoma, mune chaiyo hydraulic system, anogona kuve nemhedzisiro dzakasiyana pasi pemamiriro akasiyana ekushanda Uye chiitiko.
Nekuvandudzwa kwe hydraulic tekinoroji nhasi, rudzi rwehydraulic valve iri kupenya. Nyika dzakasiyana uye kunyange makambani akasiyana munyika imwe chete ane zvikamu zvakasiyana zve hydraulic valves. Mupepeti wechinyorwa chino anoita pfupiso pfupi zvichienderana nemhando dzemavharuvhu akajairwa pamusika kuti ataure:
1. Mavharuvhu enzira imwe anogona kukamurwa kuita mavharuvhu enzira imwe chete uye mavharuvhu anodzorwa nemavharuvhu enzira imwe chete. Iwo akajairwa-nzira imwe mavharuvhu anongobvumira kuyerera kwemvura kuti ipfuure munzira imwe, uye iyo hydraulic-inodzorwa nzira imwe-vhavha inogona zvakare kuyerera ichidzokera kumashure pasi pemhedzisiro yekumanikidza mutyairi.
2. Ivhavhavhavha yevhavha inogona kugamuchira kuyerera kwemvura kubva kune maviri akasiyana masosi uye kuendesa iyo yakanyanya kudzvanywa kune imwechete yekubuda. Shuttle mavharuvhu anowanzo shandiswa mukuremedza sensing maseketi uye mabhureki mafuta maseketi. Kusanganisira bhora mhando, chigaro vharafu mhando uye spool vharafu mhando.
3. The overflow valve ine kushandiswa kwakasiyana muzviitiko zvakasiyana. Semuyenzaniso, muhuwandu hwepombi throttling speed regulation system, chivharo chekufashukira chinoshandiswa kuchengetedza kudzvinyirirwa kwe hydraulic system (kureva kuti, kubuda kwepombi ye hydraulic) nguva dzose, uye kupfachukira kuyerera kwakanyanya kwepombi ye hydraulic kudzokera ku tangi. Panguva ino, chivharo chekufashukira chinoshandiswa pakugadzirisa nguva dzose. Kushandisa valve.
4. Ivhavha inoderedza kudzvinyirira ivhavha yekudzivirira iyo inoshandisa mvura inoyerera ichiyerera nepakati nepakati kuti ibudise kurasikirwa kwekumanikidza, kuitira kuti kubuda kwemhepo kuderera kudarika inlet pressure. Maererano nezvinodiwa zvakasiyana-siyana zvekugadzirisa, kuvhara kwevhavha yekudzivirira kunogona kugoverwa kuva nguva dzose yekuderedza kuderedza valve, chiyero chakagadziriswa chinoderedza valve uye yakagadziriswa yakasiyana-siyana inoderedza valve.
5. Basa revhavha yekutevedzana ndeyekushandisa mafuta ekumanikidza sechiratidzo chekutonga kuti udzore uye kubva kune mafuta emagetsi. Inopihwa zita nekuti inoshandiswa kudzora kutevedzana kwezviito zveakawanda actuators. Sequence mavharuvhu akakamurwa kuita zvakananga-kuita uye mutyairi-anoshanda mhando.
6. The counterbalance valve ndechimwe chezvinhu zvisinganyanyi kuvimbiswa mu hydraulic industry. Vanhu vazhinji vanofarira kuomesa sarudzo yevhavhavhavha, uye saka vanoramba kuita sarudzo.
